It’s officially October and that means it’s time to highlight the October Birthstone!
There are two in October: Tourmaline which stands for Strength & Opal which stands for Hope.
Tourmaline has become a favorite gemstone because it comes in a variety of colors and can be suited to almost anyone’s taste.
Tourmaline also is known for displaying several colors in the same gemstone. These bi-color or tri-color gems are formed in many combinations; gemstones with clear color distinctions are highly prized.
One multi-color variety is known as watermelon tourmaline, and features green, pink, and white colors bands; to resemble its namesake, the gemstone is cut into thin slices having a pink center, white ring, and green edge. Tourmaline is found in many localities including Brazil, Afghanistan, East Africa, and the USA. Info source here.
The name opal derives from the Greek Opallos, meaning “to see a change (of color).” Opals range in color from milky white to black with flashes of yellow, orange, green, red, and blue.
An opal’s beauty is the product of contrast between its color play and its background. Opal is a formation of non-crystalline silica gel that seeped into crevices in the sedimentary strata. Through time and nature’s heating and molding processes, the gel hardened into the form of opals. The opal is composed of particles closely packed in spherical arrangements. When packed together in a regular pattern, a three-dimensional array of spaces are created that give opal its radiance. Info source here.
